Variation in the use of minimally invasive bariatric surgery

Abstract Background Obesity is a significant public health problem in the United States. Despite the known benefits of bariatric surgery, most patients eligible for bariatric surgery do not receive it. Access to minimally invasive bariatric surgery (MIS), the surgical gold standard, may be a limitation. Objectives We investigated geographic variation in the utilization of laparoscopy for bariatric surgical procedures. Methods We utilized a unique 3-state inpatient database. Adult patients receiving initial bariatric surgery were included. Patients were divided into hospital service areas (HSAs). Rates of MIS utilization in each HSA were calculated. HSAs were divided into quintiles of utilization. Patient and hospital characteristics were compared across quintiles. Results Over the 5-year study period, 127,008 patients received bariatric surgery. MIS technology was available in all HSAs. MIS was performed in 88.4% of procedures and was performed in 70.6% of patients in the lowest quintile compared with 97.0% in the highest ( P
